====== Upgrading From V1 ADOdb Session Handling ======
===== The Improved Session Handler =====

In ADOdb 4.91, we added a new session handler, in adodb-session2.php. It features the following improvements:

  * Fully supports server farms using a new database table format. The previous version used the web server time for timestamps, which can cause problems on a system with multiple web servers with possibly inconsistent times.
  * The new version uses the database server time instead for all timestamps.
  * The older database table format is obsolete. The database table must be modified to support storage of the database server time mentioned above. 
  * Also the field named DATA has been changed to SESSDATA. In some databases, DATA is a reserved word.
  * The functions ''dataFieldName()'' are ''syncSeconds()'' are obsolete.
